Scenario : You have made the decision to migrate all your operations onto WebLogic
Server. An application has been chosen from each department for the initial phase of
migration one from each of Sales, Marketing, Accounts, and Customer Service. The
applications will be deployed as individual EAR files to a cluster of WebLogic Server 9.x
instances, each with a pool of connections to an Oracle 10g database that provides
corporate and departmental data services. The database team hopes to upgrade the
database to use Oracle RAC (Real Application Clusters) shortly, which will require you to
configure multiple sets of connections. Connectivity to the existing Service Engineer
Dispatch system is via a JMS message bridge. When a service engineer calls in with a
report, a message is sent via JMS to the Customer Service application deployed in
WebLogic Server. The customer record in the Customer Service database must be
updated with details from the message. It is important that the message is not lost
because the call management system is not able to resend messages. To address this,
the Customer Service application is accessing a persistent JMS Queue using an XA
compatible connection factory.
In the future, each department will have its own schema within the Oracle database and the
developers are writing their code with this in mind. However, for now, it has been decided
to store all data in a single, company-wide schema. Which of the following approaches will
make a future move to multiple schema simple, while making the most efficient use of
resources today?
A. Deploy an application-scoped Data Source module with each application.
B. Deploy a Data Source system module and assign it multiple JNDI names.
C. Deploy each department's application to its own WebLogic server.
D. Deploy a Data Source system module for each department's application.
